Deployment with Docker

Overview of this book

Deploying Docker into production is considered to be one of the major pain points in developing large-scale infrastructures, and the documentation available online leaves a lot to be desired. With this book, you will learn everything you wanted to know to effectively scale your deployments globally and build a resilient, scalable, and containerized cloud platform for your own use. The book starts by introducing you to the containerization ecosystem with some concrete and easy-to-digest examples; after that, you will delve into examples of launching multiple instances of the same container. From there, you will cover orchestration, multi-node setups, volumes, and almost every relevant component of this new approach to deploying services. Using intertwined approaches, the book will cover battle-tested tooling, or issues likely to be encountered in real-world scenarios, in detail. You will also learn about the other supporting components required for a true PaaS deployment and discover common options to tie the whole infrastructure together. At the end of the book, you learn to build a small, but functional, PaaS (to appreciate the power of the containerized service approach) and continue to explore real-world approaches to implementing even larger global-scale services.

Continuous integration/Continuous delivery

As you make more services, you will notice that manual deployments of changes from source control and builds are taking up more time due to the need to figure out which image dependencies belong where, which image actually needs rebuilding (if you run a mono-repo), if the service changed at all, and many other ancillary issues. In order to simplify and streamline our deployment process, we will need to find a way to make this whole system fully automated so that the only thing needed to deploy a new version of services is a commit of a change to a branch of your code repository.

As of today, the most popular automation server called Jenkins is generally used in such function to do this build automation and deployment of Docker images and infrastructure but others like Drone, Buildbot, Concoure, etc have been rising fast through the ranks of very capable software CI/CD tooling too but none have so far reached the same acceptance levels from the industry...
